Some people were probably on a shopping adventure and did not buy anything from you. Do not ignore these people. Find out their needs and preferences by going through logs and camera at your store. When reminding a customer or potential customer, you should address specific aspects of the business. It is important to familiarize with their choices as basis of your remarketing technique.
Of course, they noticed your store because of marketing strategies. Even if they did not buy, they were at least attracted. Do not take this for granted. While remarketing is applicable both in online and physical stores, it is more effective if you have an online shop. It is easy to identify the type of customers that were frequent in your store during the holidays hence develop a suitable remarketing strategy.
Google remarketing ads is one of the effective ways of identifying and reaching out to such people. The strategy can also focus on the average amount spent by shoppers in a specific period, in this case, during the holidays.
